The structure of the sheath surrounding a cylindrical or spherical body immersed in an isotropic collisionless plasma is investigated for a wide range of parameters corresponding to regions in space where the electron photoemission by the surface can produce small, strong, or even dominant effects (in this last case, the photoemission is also assumed to have cylindrical or spherical symmetry). The collected currents are also considered.
